Such a nice place to stay in Bangkok :)
My family stayed in Eric's apartment for 8 nights. It was the first time for me to use airbnb so, before I checked in, I had a bit worries. However, Eric responded to my message always quickly and he explained how to check in his apartment. Also, during our stay, he took care of facilities in the apartment.
When it comes to the location, it is a bit far from the public transportation such as BTS and MRT. But, we could get to the place by taxi very easily. Also, there was a big shopping center, which is called Metro West Town. There was a big market and you can buy anything you need. Additionally, swimming in the pool near the building was my favorite part of my stay.
I really recommend you to stay in Eric's place. Your stay in Bangkok will be amazing!
